REEM-B can walk while carrying up to 13kg, the record for a
humanoid robot. It uses mics, stereoscopic cameras and sensors to
gauge depth and map REEM-B's surroundings. It can also recognise
individuals by their voices and faces. PAL Robotics's eventual aim
is for REEM-B's descendants (REEM-C is currently in development) to
be available for sale or rent as autonomous service robots.
